Gardner Spring 36079G Precision Compression Spring

Product Description

The GARDNER SPRING 36079G is a precision compression spring manufactured from music wire (AISI 302 / ASTM A228 / ASTM A313) with a plain silver finish. It measures 0.42 inches outside diameter and 0.875 inches free length, with a wire diameter of 0.047 inches and a solid height of 0.33 inches. The spring delivers a rated spring rate of 28 pounds per inch and a maximum work load of 15.5 pounds. Closed and ground ends provide stable seating and consistent load transfer. This type of small-diameter precision spring is used in mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications.

The GARDNER SPRING 36079G suits applications requiring a compact, high-cycle compression element with predictable force characteristics. Its precision tolerances make it appropriate for use in valve assemblies, actuator mechanisms, control components, and similar light-duty mechanical systems. The closed and ground end configuration ensures flat, square seating against mating surfaces, which is important for maintaining consistent load alignment in service. Installers and assembly technicians working in trade and light industrial settings will find this spring sized for tight-clearance cavities requiring a hole diameter fit of approximately 0.437 inches.

Key Features

• Closed and ground ends for flat, square seating and stable load transfer
• Spring rate of 28 pounds per inch for consistent, predictable deflection
• Maximum work load of 15.5 pounds (68.95 N)
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Outside diameter of 0.42 inches fits cavities sized to approximately 0.437 inches hole diameter
• Plain silver finish suitable for general mechanical environments

Compatibility

Designed as a precision compression spring for use in mechanical assemblies where a 0.42-inch OD, 0.875-inch free length, closed and ground end spring with a 28 pound-per-inch spring rate is specified.

Installation Notes

Installation is performed by qualified mechanical assemblers or trade technicians. De-energize and depressurize any system before replacing compression springs in valve or actuator assemblies. Verify that the seating cavity matches the specified hole diameter of 0.437 inches and that the spring is seated squarely on both ends to maintain proper load alignment. Do not compress the spring beyond its solid height of 0.33 inches during installation.
